Standard DomainNet: We refer the subset of DomainNet used in [1]} as standard DomainNet. This subset consists of 4 domains (Real, Clipart, Sketch, and Painting) and 126 categories. Of all possible domain pairs (source-target), 7 are chosen for evaluation. Further, two different semi-supervised settings, 1-shot and 3-shot, are created by keeping the labels for 1 and 3 samples per class while discarding the labels for the rest. We use the same dataset splits as [1]}.
